I came across hundredpushups.com and found the idea of reaching 100 pushups in 6 weeks pretty cool. At this point I can reach a max of 25 pushups in a go.

To keep a track and also to keep myself motivated, I have created a google spreadsheet to track my progress, which generates a chart in the sidebar. Finished the first day task easily.

I also checked few videos before starting, just to make sure I was doing the pushups properly.
